-' Specification of Letters Patent.

Patented'Dec. 10,1918.

Application filed April 13, 1918. Serial No. 228,317.

To all whom it may concern:

Be it known that I, CHARLES A. LEFEVRE, a citizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Can-Openers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

My invention relates to can openers and a special object of my improvements is to provide for loosening the kind of covers that are pressed into the openings of cans and retained therein by friction, the cover at its edge overlapping the top of the can.

I secure this object in the device illustrated in the accompanying drawing in which:

Figure l is a perspective view of the upper part of a'can with the cover and apparatus embodying my invention adjusted thereto.

Fig. 2 is a detail sectional view of the same.

Fig. 3 is a detail jointed rotating arm.

Fig. 4 is a sectional elevation showing the adjacent ends of cans where one is packed upon the other.

a is the cylindrical part of the can which has an inturned annular part or top a The rest of the top of the can is open and there is preferably a down-turned flange a (Fig. 2) araound the opening. I) is a cover which is concave upward and convex downward as shown, the concave part being adapted to fit closely against the inner edges of. the annularinturned portion, or top, a of the can. b is an outwardly extending flange on the cover I) which when the cover is in place rests against the upper surface of the annular portion a of the can.

At the center of the cover I secure a pivot iece 0 which may be in the nature of a l ieaded rivet. Upon the pivot c I secure a flat arm 03 which may rotate on said pivot. d is a second arm forming an extension of the arm 03 and pivoted thereto, so as to turn in a vertical plane, by means of a link d extending through eyes on adjacent ends of the arms (1 and (1 The outer endof the arm view of a part of the cover,

d is bent back marked 0Z and is is at some distance the arm (Z of the part (5 in the arc of a periphery of the upon itself in a portion bent so that its inner end from the main portion of The edge at the inner end is chamfered and is shaped circle corresponding to the cover 6, as shown in Fig. 3.

In the normal position of the arms 03 and d the latter is turned backward upon the former, a shown by dotted lines in F ig. 2 and in full lines in Fig. 4, so that the whole of both of said arms lies in the depression of the cover so that a second can may be placed upon the top of this can and lie smoothly thereon.

To loosen the cover the arm d is turned outward, as shown in Figs. 1 and 2, the edge a? is forced under the the arms d and d are rotated around the pivot 0 thus raising the flange from the annular portion a of the top of the can and loosening the cover so that it can be readily removed.

While I prefer to bend the arm d upon itself as shown and described of course the inwardly extending opening edge could be otherwise provided.

What I claim is: a

1. In combination with a can having a said cover being provided with a circular outwardly extending flange in a plane approximately parallel to the adjacent surface of the can, an arm formed of two parts, the inner part being pivoted to said cover at the center of the circle in which said flange lies so as to turn in a plane parallel to that of said flange, said outer part being provided with an inwardly extending separating edge adapted to be inserted under said flange. the outer part of said arm being movable relative to the inner part.

2. In combination with a can having a cover, said cover being provided with a circular flange in aplane approximately parallel to the adjacent surface of the can, an arm formed of two parts, the inner part being pivoted to said cover at the center of the circle in which said flange lies so as to turn in a plane parallel to that of said flange, the outer part being pivoted to the inner part so as to turn in a vertical plane at an angle to the first named plane.

3. In combination with a can havin a cover concaved outwardly, said cover being flange b and then provided with a circular flange in a plane serted under said flange, the outer part of 1 approximately parallel to that of said cover, said arm being adapted to fold within the an arm formed of two parts, the innerpart concavity of said cover for the purpose de- 10 being pivoted to said cover at the center of scribed.

5 the circle in which said flange lies, said In testimony whereof I sign this specifiouter part being provided with an inwardly cation. extending separating edge adapted to be in- CHARLES A. LEFEVRE.
